BBK LS790B Leak-Seeker Refrigerant Detector

The BBK CPS LS790B Leak-Seeker is a professional-grade electronic refrigerant leak detector designed for HVAC technicians and maintenance professionals. Combining advanced microcomputer circuitry with patented Ion-Pump sensor technology, this detector delivers unmatched sensitivity—capable of identifying leaks as small as 0.25 oz/yr (7g/yr) of HFC refrigerants. Its automatic calibration system eliminates manual adjustments, ensuring consistent accuracy across all non-combustible CFC, HCFC, and HFC gas blends.

Featuring a flexible probe for precise leak localization and a high-intensity bar graph display with over 100 computer-generated tones, the LS790B provides clear, real-time feedback on halogen concentrations. The device also includes a patented water vapor filter for stable performance in high-humidity environments, making it ideal for fieldwork in diverse conditions. With 10 user-selectable sensitivity ranges, it adapts to varying leak scenarios, ensuring reliable detection without false positives.
